Abstract Older adults and people with disabilities are two unique populations, though they intersect in their need for mobility options that are often not met by traditional transportation services. There is consensus that the government should provide assistance for older adults and people with disabilities to achieve and maintain independence.

Abstract Older adults and people with disabilities are two unique populations, though they intersect in their need for mobility options that are often not met by traditional transportation services. There is consensus that the government should provide assistance for older adults and people with disabilities to achieve and maintain independence. However, the challenge lies in addressing the many forms of mobility inequity. Population projections for the twenty-first century have sparked interest in the rights of these two populations. As the population of the United States of America ages, supporting the mobility of seniors and individuals with disabilities will become imperative to maintaining their quality of life. One existing federal grant, Section 5310: Enhanced Mobility for Seniors and Individuals with Disabilities (49 U.S.C. 5310) provides formula funding for services that provide transportation options to older adults and people with disabilities. While the 5310 program provides crucial funding to non-profits and government agencies to support mobility options for older adults and people with disabilities, it does not address the full scope of mobility issues faced by these two communities. This thesis project provides a thorough analysis of this grant from the federal legislation it is founded on, to the local administration of this grant as applied by the Maricopa Association of Governments (MAG). Finally, this thesis looks at emerging technology with the potential to revolutionize mobility, along with sobering historical context of the barriers faced older adults and people with disabilities.

Community gardens are used worldwide to promote sustainable, urban living. They can be used to improve the physical, mental, emotional, and social health of the gardeners and volunteers who utilize their grounds. The gardens may also have a positive impact on the local environment and wider community. This study examines a community garden seeking to expand its involvement in the local neighborhood and searching for ways to include local residents in garden related activities. To this end, the garden was waiting for approval on their non-profit, 501(c)3 status, and was seeking additional data on local residents and perceptions of the garden's activities. This thesis first reviews the literature on the benefits community gardens provide for the individuals living in their communities and their impact on urban development. The thesis then turns to an analysis of one garden, Mesa Urban Garden, rooted in the Downtown District of Mesa, Arizona, and how they are impacting their neighborhood and how garden organizers can respond in new and creative ways to local residents.

The ecological benefits provided by trees include improving air quality (Nowak, et. al., 2006), mitigating climate change by sequestering carbon (Nowak, 1993), providing animal habitats (Livingston, et. al., 2003), and reducing heat (Edmonson, 2016), among others.

The ecological benefits provided by trees include improving air quality (Nowak, et. al., 2006), mitigating climate change by sequestering carbon (Nowak, 1993), providing animal habitats (Livingston, et. al., 2003), and reducing heat (Edmonson, 2016), among others. Trees also provide numerous social benefits, impacting urban sustainability in particular by improving human health (Salmond, 2016), aesthetically and economically improving neighborhoods (Torres, 2012), and contributing to thriving communities by creating gathering spaces and even reducing crime (Abraham, et. al., 2010). Because of the tremendous potential of trees to provide social and ecological services, particularly in urban areas, tree planting has become an important facet of many sustainability initiatives. This thesis assesses one such initiative aimed at planting trees for the diverse benefits they provide. Valley Permaculture Alliance (VPA), a nonprofit based in Phoenix, Arizona, is known for its Shade Tree Program. The author conducted an internal, quantitative assessment of the program between August and December of 2015. The assessment included evaluation of several indicators of ecological and community health related to the presence of shade trees, culminating in a report released in 2016. This paper evaluates the use of sustainability indicators in the VPA assessment as well as their value in different types of organizations. It culminates with an assessment of VPA's strengths, challenges faced by the organization, and suggestions for its future development.

This creative project is a collection of profiles focused on Arizona nonprofits and refugees. The profiles share stories of refugees, volunteers, employees and others involved in the community serving refugees. Nonprofits are a vital resource for refugee resettlement. These organizations offer services to support refugees as they transition into new communities. Some services include: housing, English language learning, cultural orientation, job placement, medical treatment, education, and farming. Each of these programs support resiliency for refugees and for the communities in which they live. We Are Resilient was created first, to show the important role nonprofits have in serving refugees. Second, to connect people to a few of the stories and experiences within the Arizona refugee community. And third, to build understanding of the strength refugees bring to communities of Arizona and by extension the country. Visit weareresilientaz.com to learn more.

This honors thesis is focused on two separate catalysis projects conducted under the mentorship of Dr. Javier Pérez-Ramírez at ETH Zürich. The first project explored ethylene oxychlorination over supported europium oxychloride catalysts. The second project investigated alkyne semihydrogenation over nickel phosphide catalysts. This work is the subject of a publication of which I am a co-author, as cited below.

Project 1 Abstract: Ethylene Oxychlorination
The current two-step process for the industrial process of vinyl chloride production involves CuCl2 catalyzed ethylene oxychlorination to ethylene dichloride followed by thermal cracking of the latter to vinyl chloride. To date, no industrial application of a one-step process is available. To close this gap, this work evaluates a wide range of self-prepared supported CeO2 and EuOCl catalysts for one-step production of vinyl chloride from ethylene in a fixed-bed reactor at 623 773 K and 1 bar using feed ratios of C2H4:HCl:O2:Ar:He = 3:3 6:1.5 6:3:82 89.5. Among all studied systems, CeO2/ZrO2 and CeO2/Zeolite MS show the highest activity but suffer from severe combustion of ethylene, forming COx, while 20 wt.% EuOCl/γ-Al2O3 leads to the best vinyl chloride selectivity of 87% at 15.6% C2H4 conversion with complete suppression of CO2 formation and only 4% selectivity to CO conversion for over 100 h on stream. Characterization by XRD and EDX mapping reveals that much of the Eu is present in non-active phases such as Al2Eu or EuAl4, indicating that alternative synthesis methods could be employed to better utilize the metal. A linear relationship between conversion and metal loading is found for this catalyst, indicating that always part of the used Eu is available as EuOCl, while the rest forms inactive europium aluminate species. Zeolite-supported EuOCl slightly outperforms EuOCl/γ Al2O3 in terms of total yield, but is prone to significant coking and is unstable. Even though a lot of Eu seems locked in inactive species on EuOCl/γ Al2O3, these results indicate possible savings of nearly 16,000 USD per kg of catalyst compared to a bulk EuOCl catalyst. These very promising findings constitute a crucial step for process intensification of polyvinyl chloride production and exploring the potential of supported EuOCl catalysts in industrially-relevant reactions.

Project 2 Abstract: Alkyne Semihydrogenation
Despite strongly suffering from poor noble metal utilization and a highly toxic selectivity modifier (Pb), the archetypal catalyst applied for the three-phase alkyne semihydrogenation, the Pb-doped Pd/CaCO3 (Lindlar catalyst), is still being utilized at industrial level. Inspired by the very recent strategies involving the modification of Pd with p-block elements (i.e., S), this work extrapolates the concept by preparing crystalline metal phosphides with controlled stoichiometry. To develop an affordable and environmentally-friendly alternative to traditional hydrogenation catalysts, nickel, a metal belonging to the same group as Pd and capable of splitting molecular hydrogen has been selected. Herein, a simple two-step synthesis procedure involving nontoxic precursors was used to synthesize bulk nickel phosphides with different stoichiometries (Ni2P, Ni5P4, and Ni12P5) by controlling the P:Ni ratios. To uncover structural and surface features, this catalyst family is characterized with an array of methods including X-ray diffraction (XRD), 31P magic-angle nuclear magnetic resonance (MAS-NMR) spectroscopy, and X-ray photoelectron spectroscopy (XPS). Bulk-sensitive techniques prove the successful preparation of pure phases while XPS analysis unravels the facile passivation occurring at the NixPy surface that persists even after reductive treatment. To assess the characteristic surface fingerprints of these materials, Ar sputtering was carried out at different penetration depths, reveling the presence of Ni+ and P-species. Continuous-flow three-phase hydrogenations of short-chain acetylenic compounds display that the oxidized layer covering the surface is reduced under reaction conditions, as evidenced by the induction period before reaching the steady state performance. To assess the impact of the phosphidation treatment on catalytic performance, the catalysts were benchmarked against a commercial Ni/SiO2-Al2O3 sample. While Ni/SiO2-Al2O3 presents very low selectivity to the alkene (the selectivity is about 10% at full conversion) attributed to the well-known tendency of naked nickel nanoparticles to form hydrides, the performance of nickel phosphides is highly selective and independent of P:Ni ratio. In line with previous findings on PdxS, kinetic tests indicate the occurrence of a dual-site mechanism where the alkyne and hydrogen do not compete for the same site.

Community Action Research Experiences (CARE) partnered with Mission of Mercy, a faith-based nonprofit organization that provides free medical care services to uninsured and underinsured individuals throughout the Phoenix valley. A needs assessment was conducted on Mission of Mercy's patient population and data collected over a two month long period, in which 91 completed surveys were collected. Participants were between the ages of 18 to over 65 and were largely Hispanic/Latino, followed by White/Anglo and Black/African American. The results indicate that there is need for increased patient education which could be satisfied by implement an incentive program. A need for a program specific to high blood pressure was also found. Participants were interested in dental services being offered, a service that is currently not offered through the Arizona chapter of Mission of Mercy. The study also showed that respondents were satisfied with the level of care received at Mission of Mercy.
